The aim of this paper is to improve power quality in a multimicrogrid (MMG) with high penetration of various distributed generators in island and interconnected mode using an improved custom power device called distributed power condition controller (DPCC). The DPCC is an improved, low‐cost, reliable combined custom power device to compensate simultaneously the voltage drop, harmonic distortions, and feeder losses in the MMG, which includes the verity of nonlinear source. It has great market potential and has been selected as the solution for more specific applications. The capability of the DPCC is increased by discrete fuzzy‐based PI controller. In addition, the power injection model of DPCC is presented. Two different case studies corresponding to the island mode and high penetration of renewable generation and nonlinear load in connected mode are considered. According to theoretical studies and simulation results, DPCC successfully improves power quality of the MMGs.
